Prasanna Kumar Kalever 812003eb45 util: fix bug in DeviceEncryptionStatus() 
With Luks1 device:
$ cryptsetup status /dev/mapper/crypto-rbd0
/dev/mapper/crypto-rbd0 is active and is in use.
  type:    LUKS1
  cipher:  aes-xts-plain64
  keysize: 512 bits
  key location: dm-crypt
  device:  /dev/rbd0
  sector size:  512
  offset:  4096 sectors
  size:    4190208 sectors
  mode:    read/write

With Luks2 device:
$ cryptsetup status /dev/mapper/crypto-rbd0
/dev/mapper/crypto-rbd0 is active and is in use.
  type:    LUKS2
  cipher:  aes-xts-plain64
  keysize: 512 bits
  key location: dm-crypt
  device:  /dev/rbd0
  sector size:  512
  offset:  32768 sectors
  size:    4161536 sectors
  mode:    read/write

This could lead to failures with unmap in the NodeUnstageVolume path
for the encrypted volumes.

Ceph CSI

Go Report Card

This repo contains Ceph Container Storage Interface (CSI) driver for RBD, CephFS and kubernetes sidecar deployment yamls of provisioner, attacher, resizer, driver-registrar and snapshotter for supporting CSI functionalities.

Overview

Ceph CSI plugins implement an interface between CSI enabled Container Orchestrator (CO) and Ceph cluster. It allows dynamically provisioning Ceph volumes and attaching them to workloads.

Independent CSI plugins are provided to support RBD and CephFS backed volumes,

  • For details about configuration and deployment of RBD plugin, please refer rbd doc and for CephFS plugin configuration and deployment please refer cephfs doc.
  • For example usage of RBD and CephFS CSI plugins, see examples in examples/.
  • Stale resource cleanup, please refer cleanup doc.

NOTE:

  • Ceph CSI Arm64 support is experimental.

Project status

Status: GA

Supported CO platforms

Ceph CSI drivers are currently developed and tested exclusively on Kubernetes environments. There is work in progress to make this CO independent and thus support other orchestration environments in the future.

NOTE:

  • csiv0.3 is deprecated with release of csi v1.1.0

Support Matrix

Ceph-CSI features and available versions

Please refer rbd nbd mounter for its support details.
